I have a fuel injection conversion project in mind, using either a Megasquirt or Canems programmable control system.
My old non-crossflow, 850cc four pot engine presently has a single semi-downdraught SU type carburettor. The carb is fitted on a heated swan-neck adapter which takes the mixture...
I've been having a discussion on another forum about oil pressure limits. Our old 850 engines have a relief valve that is supposed, by design, to open at 45 psi, according to published data. On my engine the gauge pressure shows 55-65 psi at start from cold, then settles down to about 45-55 psi...
I've just stripped out the big-end shells from my 1986 made (but remanufactured in '99), tuned 850 cc trials car engine, to investigate a rattle which suddenly occcurred and rapidly got worse. No. 4 conrod had quite a lot of play in the bearing, the other three less so.
The bearing faces of the...
I have a small car (a Liege) which uses an 850 cc engine and a small 4 speed gearbox, the latter "not being known for its reliability". At Mallory Park racetrack during an endurance event the oil badly overheated and the gearchange became more tricky. The car eventually suffered a bad gear...
I have a question, more out of personal curiosity than anything.
Does anyone here still prefer to use "old fashioned" mechanical points ignition, or has everyone gone over to electronics these days, even for old engines that were designed for points. If any strong views, please put them forward...
My wife runs her own small floristry business. She bought a 4 year old, ex-UK Post Office, Ford 1800cc diesel engined (non-turbo) van. It has always been a bit reluctant to start when the engine is cold, but it fires up much better once the engine has run once for the day. I notice it's...
My apology if this is the incorrect forum for this question but I could find no other threads on brakes elsewhere.
I have a kit car that uses twin leading shoe drum brakes on the front, single leading shoe drums at the rear.
The problem was that the car was over-braked at the front. The front...
One of the two helicopters I fly for a living (both are Sikorsky S-76s) uses Mobil 254 (primarily a turbine engine oil) in the main, intermediate and tail rotor gearboxes.
The other heli uses ATF in the gearboxes, (Mobil 254 again in the engines). Both oils have similar viscosities judging by...
I have a normally aspirated Reliant 862 cc car engine (petrol/gasoline, spark ignition), remanufactured from one which (unknown to me at that time) already had a CR of 10.5 to 1.
Because the car I built it for is a competition car (it's called a Liege, for on and off-road trials), I wanted the...
